摘要: The pair correlation between spins considered at different times in a ferromagnetic crystal is used to derive general formula for the angular and energy distribution of magnetically scattered neutrons. qualitative properties are established various temperature ranges number characteristic features scattering its variation thus accounted for. From study long-range part an explicit expression derived "critical magnetic scattering" produced neighborhood Curie point by large spontaneous fluctuations magnetization.
